439910 ÷ 14 
The aim is to understand the frequency of 14 in 439910.

On to step 1:
4 divided by 14 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 14

On to step 2:
14 can be fit into 43 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 42 from 43 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 14

Going ahead to step 3:
The number 14 fits into 19 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 14 from 19 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 14

Let's proceed to step 4:
14 can be fit into 59 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 314.0
Subtracting 56 from 59 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 14

Advancing to step 5:
31 divided by 14 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 3142.0
If we subtract 28 from 31, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 14

Advancing to step 6:
14 goes into 30 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 31422.0
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 14, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 31422.1
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 31422.14
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 14, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 31422.142
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
If we divide 120 by 14, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 31422.1428
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 14, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 31422.14285
If we subtract 70 from 80, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
14 goes into 100 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 31422.142857
The remainder is 2 after subtracting 98 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 31422.1428571
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
14 can be fit into 60 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 31422.14285714
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 31422.14285714 and a remainder of 4e-09.
